Two mandarin duck foods, namely a conventional food and a reproductive food are arranged. Based on the food consumption of a single mandarin duck per day, the food formula comprises:

conventional food formulations: 60g of green vegetables, 10g of apples, 40g of granulated feed, 40g of steamed corn bread and 10g of corns.

The formula of the breeding period food comprises the following components: 60g of green vegetables, 10g of apples, 40g of granulated feed, 40g of steamed corn, 10g of corn, 5g of cooked beef powder, 10g of cooked soybeans, 10g of cooked egg and 20 g of malt.

The upper and lower floating ranges are within 10% according to the formula when the feed is fed at ordinary times.

In the previous research, the designer feeds the chicken in a single mode, namely feeds the chicken in the conventional food formula in a reproductive period or a non-reproductive period, wherein the hatching rate is 20-35%, and the individual reproduction rate is 5%. Subsequently, the designer uses a feeding method of two stages of a non-breeding period and a breeding period, the hatching rate is 90%, and the individual breeding rate is increased to 87%.

Example 4 optimization of cage design

The designer finds that the breeding of the mandarin ducks is promoted for a long time, needs to provide living places and proper activity places with proper sizes for the mandarin ducks, and needs to consider the habit of the mandarin ducks and some characteristics in the aspect of special safety. The designer finds that the height of the nest box plays an important role in mandarin duck breeding.

Mandarin duck is raised by using the cages and nest boxes manufactured in the foregoing embodiments 1 and 2 and the food of embodiment 3, and mandarin duck breeding conditions under the condition that the average floor area and cage height of a single mandarin duck are different (i.e. under different raising densities) are observed, and are shown in table 2 in detail.

TABLE 2 Individual reproduction Rate for different cultivation conditions

According to the table 2, the average floor area of a single mandarin duck is 1.5-3.2 square meters, so that an ideal individual reproduction rate can be realized, wherein 1.5-2.4 square meters are particularly ideal. From the viewpoint of the height of the nest box, the height is preferably 1.5 to 3 m.

The designer finds that most nest boxes higher than 3 meters are discarded by mandarin ducks; less than 1 meter is also mostly discarded, which may be due to mandarin duck being very sensitive to self-security as well as to security of offspring.

Summary of the invention

To sum up, according to the statistics that this designer breeds in batches many, do not implement the utility model under the condition of relevant scheme, the rate of hatching is 20 ~ 35%, and is implementing under the condition of relevant scheme, the rate of hatching improves to 90%.

According to the statistics that this designer breeds many batches, do not implement the utility model under the condition of relevant scheme, individual reproduction rate 5 ~ 10%, and implementing under the condition of relevant scheme, individual reproduction rate improves to 87%.
